To @ZZ whom may eminemv Be it known 'that L FRANK Ricamo, e eil-izen ofthe United Ste-tes, residing at Manent, in the county of Bibl) andStarte of Georgian lieve invented o1' discovered `eeiinin new and usefulimprovements in Founiein Pens, of which the following is espeoilieetion, i'e'feienee being had tlieiein to die eccoinpanying1drawing.

To make a tight joint at the outer end of the ink chamber within theouter casing l part'12, a bushing 27 of' cork or other suitH ablematerial is tightlvfittedwitliin said casing contiguous to the sleeve24, and said bushing is preferably retained in place, against inwardmovement, by a washer 28 of hard rubber or other suitable materialabutting against a shoulder at 12L formed on said casing part.

To fill the pen the cap legis unscrewed from the casing 12 and thepiston or pump sleeve 21 is then unlocked from the holding sleeve 24 bya partial rotation of the `knob 2'1), causing the ends of the lockingpin 26 to register with the longitudinal parts of the bayonet jointslots 25. This partial rotation of* the said knob and the piston or pumpsleeve therewith closes the valve ai,- orded by the openings 16 and 18in the parts 15 and 17,. and the piston or pump sleeve 21 is then drawnout to lill the ink chamber oi the'pen.

ln thus filling said ink chamber the ink flows into the chamber of thepistonorpump sleeve 21, and thence into the chamber oi the casing 12.When the said piston oi' pump 21 is'iiorced inward more or less airescapes `through the tube` I 15L communicating with the chamber of thepen-holding part 18 and 'the inlet and outlet with which said part 13 isprovided.

Fromthe foregoing it will be understood that the present inventionaliiords an improved eonstruetion of the valve' and valveoperatingdevices which are-deemed to be preferable to the constructions showii inmy said Patent No. 1398,800, hereinbefore referred to.

Having thus described my invention I claim and 'desire to secure .byLetters Patent:

l. In a fountain pen, the combination with an outer casing ali'ording anink chamber, of a valve comprising two sleeves provided with openings,one of said sleeves being fixed relative to the pen-holding member andthe other being rotatable on said fixed sleeve to enable said openingsto registerwith each other, when desired, a piston sleeve slidinglymounted within said easing, and means whereby said valve may be openedor closed by a partial rotation of said piston sleeve.

2. ln a fountain pen, the combination with an outer easing affording anink chainber, of a sleeve fixed within said vcasing and provided withone or more openings, a rotatable valve sleeve mounted on said fixedsleeve and also provided with one or more openings which maybe caused toregister with the opening orl openings in said fixed sleeve, said valvesleeve having side projecinname tions, a piston sleeve tted to slidewithin said casing and'liaving a closed outer end, said piston sleevehaving means adapted to engage the said projections to enable said valvesleeve to be partially rotated by said piston sleeve, and means forlocking said piston sleeve against longitudinal movement.

3,1n-a fountain pen, the combination with an outer casing affording anink chainber, of a sleevel xed within said casing -and provided with oneor more openings,

tated by said piston sleeve, and means tor locking said piston sleeveagainst longitudinal movement, said locking sleeve consisting of asleeve fixed to said outer casing and provided with a bayonet joint slotor slots, and one or more pins, connected with said piston sleeve and`adapted to enter said slot or slots. e

ln a fountain pen, the combination with an outer casing affording lanink chamber, 'ot a valve comprising two sleeves provided' with openings7one of saidsleeves being iiired relative to the pen-holding member andthe other of said sleeves being rotatable on said hired sleeve to enablethe valve to be opened and closed, a piston sleeve slidingly mountedwithin said casing, means whereby said valve may be opened and closedby'a partial rotation of said piston sleeve, and means for locking saidpiston sleeve against longitudinal movement. y

5. In a fountain pen, the combination with an outer easing affordinganink chamber, of a valve comprising two sleeves pro- -vided withopenings, one of said sleeves being rotatively mounted on the other toenable thevalve to be opened and closed, a

with an outer casing affording an ink chain-P ber, et a valve comprisingtwo sleeves provided. with openings, one of said sleeves belil() ingrotatively mounted'on the other to enable the valve to be opened andclosed, a piston sleeve slidingly mounted within said casing, meanswhereby said valve may be opened and closed by a partial rotation ofsaid piston sleeve, means for looking said piston sleeve againstlongitudinal movement, said locking means comprising a sleeve screwedinto the outer end of said Casing and pro'ided with a circumferentialflange and with a bayonet joint slot or slots, said piston sleeve beingprovided' with a knob closing its outer end, one or more pins carried bysaid knob and entering' said slot or slots, and a cap fitted to theouter end of said locking sleeve and aording a housing for said knob.

7. ln a fountain pen, the oombination with an outer casing aording anink chamber, of a valve comprising two sleeves provided with openings,one of said sleeves be-4 ing rotatively mounted on the other to en ablethe valve to be opened and closed, a piston sleeve slidingly mountedwithin said casing, means whereby said Valve may be opened and closed bya partial rotation of said piston sleeve, means for locking said pistonsleeve against longitudinal moveu ment, a packing bushing within saidoasing Contiguous to said locking sleeve, and means for preventing saidbushing from being displaced inwardly in said casing.

In testimony whereof ll aix my signa= ture.
